IMPROVEMENT IN WEATHER-STRI PS.

Specification forming part of Letters Patent No. 197,974, dated December11, 1877; application filed July 7, 1877.

er-strips, to be applied more particularly to the bottoms of doors andwindows opening on hinges. It consists of aplate or strip of metaltongued along its upper edge to fit into a corresponding groove in thedoor, said strip be ing hinged to the lower rail of a door or win dow,to be kept clear of the carpet-strip when open by a bent spring,provided with a slot at its lower end and secured to the door at itsupper end.

The weather-strip, when the door or window is closed, fits snugly intoarabbet formed in the lower rail of the door or window, and, extendingdownward, rests on the door-sill and against the vertical bearing formedby the edge of a carpet-strip secured between the jambs of the opening.

Referring to the drawings, Figure l is a perspective view, showing theappearance of the device outside when the dooris closed. Fig. 2 isa'perspective view, showing the door partly opened. Fig. 3 is ahorizontal section cut through door and door-jambs, and Fig. 4 is avertical central section.

Similar reference-letters denote like parts in all of the figures.

A is the door, hung with hinges upon the janib B, and closing againstthe shoulders formed by the rabbets in the jambs B B. The sill of thedoor A has a carpet-strip, G, which, projecting above said sill,has itsouter edge out square, to form, with the door-sill, a rabbet, againstwhich rests the weather-strip when the door is closed. The carpet-stripG is capped with metal or other hard material, and secured to thedoor-sill A in the usual manner.

The lower rail of the door is cut away or rabbeted to receive the plateD, which, when in its place, has its outer face in line with outer planeof door. The depth of the weatherplate D is equal to the rabbet in thelower rail of door and the depth or height of the carpet'strip 0 abovethe door-sill A.

The door A is provided with a bent spring, E, which is screwed to saiddoor, and, extending downward, is secin'ed loosely to the weather-plateD. The spring E is provided at its lower end with a slot, at, and isheld against the strip D by a pin, 12.

The carpet-strip O is fastened to the sill of the door in such a way asthat a groove, 0, is formed between it and the jamb B, of a widthsufficient to admit the weather-plate D when the door is closed.

The rabbet in the jamb B, against which the weather-plate D bears whenthe door is closed, may be clad with metal, to give a smooth bearing tothe edge of the weatherplate which impinges against it. The upper edgeof the weather-plate is provided with a tongue to fit into a groove inthe return of the rabbet, to prevent rain, &c., from driving behind saidplate.

The operation of the device is as follows: The door being closed, theweather-plate D bears evenly against the edge 61 of the carpetstrip 0.As the door is opened inward, the spring E lifts and holds theweather-plate at about an angle of forty-five degrees, so that thecarpet-strip C may be cleared as the door moves over it. When the dooris nearly closed the lower edge of the weather-strip comes in contactwith the return of the rabbet in the jamb B, whereby the said strip isautomatically pressed inward toward the door, and, extending below thebottom of said door, it enters the groove 0, formed between the returnof the rabbet and the carpetsill O.

The strip D bearing snugly against the outer edge of the strip 0, aclose joint is formed to keep out rain, snow, wind, and dust.

I am aware that weather-strips are in use having springs moving in loopson the door, and secured to the strip, and this, broadly, I do notclaim.

I am also aware that weather-stripsheld out of the way of thecarpet-sill by springs have been closed by coming in contact with therabbet in the door-j amb, and this peculiarity,therefore, I do notclaim, broadly; but

What I do claim, and desire to secure by Letters Patent, is-

The strip D, tongued along its upper edge to fit into a correspondinggroove in the door, in combination with the carpet-sill G, met

angular at its outer edge, and forming, with the door-sill F, a rabbet,and jamb B, forming, with outer edge of carpet-strip G, the groove 0, asand for the purpose set forth.
